Health providers are sending a message to tobacco companies gearing up to fight a proposed $2-per-pack hike on cigarette taxes in Oregon: Be prepared to spend big.

On Monday, the campaign that will seek to convince voters to approve the tax increase next year unveiled nearly $9 million in contributions from seven health systems that do business in Oregon. That includes a nearly $3.3 million infusion from Washington-based Providence Health & Services, which runs eight hospitals in Oregon.
